Welcome to the Rain World Modding Wiki

This wiki was created to start to compile the RW communities modding knowledge all in one place.

Basic Modding Overview

Rain World mods come in a few varieties. The most user friendly approach is to use the official level editor to create new rooms which can be imported into the engine with relative ease. It's also possible to use the tool dnSpy to peek at the games base code and potentially make modifications or create entirely new creatures or mechanics, but given the complexity of the codebase it is extraordinarily challenging (even for an experienced C# programmer). Finally, there are a few community made tools that give you access to some of the information and allow for the placement of enemies or the tweaking of pre-existing engine variables.
